F. C. SMITH WRIST WATCH STRAP Filed March 31, 1932 Feb. 21, 1933.

Inventor Z /E'EOEE/CA C LEW/7ft Attorney- Patented Feb. 21, 1933 UNITED STATES FREDERICK C. SMITH, F SANDUSKY, OHIO WRIST WATCH STRAP Application filed March 31, 1932. Serial No. 602,342.

This invention relates to improvements in wrist watch straps.

The principal object of the invention resides. in a wrist strap for watches which when applied to the wrist of a wearer, will not slip,

either around or lengthwise of the same.

Another feature of the invention is to pro-- vide a non-slippable wrist watch strap embodying a plurality of flexibly connected metal links having a friction element on the inner side thereof to which in addition to preventing slipping of the strap, also serves as a cushion between the metal links and the wrist to insure comfort when in use.

A further object of the invention is the provision of a non-slippable wrist watch strap which is simple and inexpensive of construction and which resembles in appearance the present style of link strap.

Other objects will appear as the foregoing specification is read in conjunction with the accompanying drawing, in which:

Figure 1 is a top plan View of my improved wrist watch strap.

Figure 2 is a detail perspective view of one of the links of which the strap is formed,

the same being in an inverted position.

Figure 3 is an enlarged detail sectional view on the line 33 of Figure 1.

Figure 4 is a detail vertical sectional view of a slight modification.

Referring to the drawing by reference characters, the numeral 10 designates my improved wrist watch strap in its entirety,

which is shown in use with a wrist watch 11. The strap 10 is constructed of a plurality of ornamental metal links 12 of any desired design, connected by sets of connecting links 13 so as to render the strap flexible for snug fit upon the wrist of a wearer. The strap may be of the endless expansible link type, or of that type having a releasable fastener for connecting free ends of the strap together.

In the present instance, I have shown the links 12 as comprising afiat rectangular strap body 14 having an opening 15 centrally therein so as to lighten the weight of the strap and afford circulation of air to the wrist of the wearer,'thus minimizing the area of the strap which may be in contact with the wearers wrist. In plan, the links resemble rectangular shaped frames.

Secured to the inner sides of the body 14 of each link is a friction member 16 which according to the design of the links is rectangular in plan, and of a size to be disposed inward of the inner and outer edges of the frame shaped body 14. The friction member 16 is preferably made of rubber so as to act as a cushion as well as a friction element. The rubber friction member 16 is preferably cemented to the inside of the body 14 although other means of attaching the friction member may be used if desired.

From the foregoing description, it will be apparent that I have provided a flexible metal wrist watch strap provided with a friction element on the inside thereof, which when the strap is affixed to the wrist of the wearer serves to prevent accidental slipping 7 of the same. It will be appreciated that it is desirous to apply the strap to the wrist of the wearer so that the face of the watch may be seen by looking at the top of the wrist, but the present style of straps tend to slip and thus the watch shifts from its proper position, making it necessary for the wearer to turn the strap back to proper position before the watch may be viewed. This is a great annoyance to wearers of wrist watches which will be overcome by the use of the improved strap herein shown and described.

In Figure 4 of the drawing, I have illustrated a slightly modified form of my invention wherein the numeral 15' designates the body of a link similar to that shown at 14 in the preferred form, with the exception that the inner side of the same is provided with a recess 17 which is filled with an adhesive 18 in which the rubber friction member 16 is set. Such construction provides a positive bond between the body of the link, and the friction member. The inner face of the friction member 16 is disposed within the recess 17 while the outer surface extends beyond the plane of the inner face of the link body.

While I have shown and described what I believe to be the preferred embodiment of my invention, I wish it to be understood that any changes as come within the scope of the appended claims may be resorted to if desired.

Having thus described the invention, What I claim as new and desire to secure by Letters Patent is 1. A Wrist Watch strap comprising a plurality of flexibly connected links, and resilient friction members fixedly supported upon the inner surfaces of said links.

2. A Wrist Watch strap comprising a plurality of flexibly connected links, and rubber cushion elements mounted on the inner sides of said links.

3. A Wrist Watch strap link comprising a metal body, and a yieldable friction element fixedly secured to the inner side of said body.

4. A Wrist Watch strap link comprising a metal body, and a yieldable friction element adhesively secured to the inner side of said body.

In testimony whereof I affix my signature.

FREDERICK G. SMITH.
